Abstract: A microfiche having pinholes instead of lenses. The pinholes and thickness of the fiche are of such dimensions that the device functions as in the manner of a pinhole camera.

Abstract: An optical magnifying device employing fiber optics. When functioning as a microscope, the object plane is defined by and divided into sub-areas by the input termini of many coherent fiber bundles. Each output terminal of each bundle is provided with an objective lens which projects onto an image plane. When used as a microfiche reader, a first magnifying stage is provided, and this (first) image is in turn further magnified in the same manner. Microfiche characters of 2 micron size may be resolved by the entire system.

Abstract: An indexing construction for microfiche elements of the type wherein the microfiche is provided with integral lens elements to define a lensfiche. The improvement comprises raising the lens elements with respect to the microfiche to thereby define a plurality of upstanding positioning and indexing nodules. These nodules cooperate with complementary nodules on either a viewing screen or a harness member. By virtue of this construction both alignment of the lensfiche and indexing thereof relative to a viewing screen are facilitated.

Abstract: A microfiche structure consisting of a laminate of an opaque, apertured web sandwiched between two transparent sheets. The transparent material partially extends into each aperture to thereby define, for each aperture, an optical doublet. The laminate may be continuously formed by compression, as by rolls.

Abstract: A microrecord in which a plurality of data sets are formed on a record medium, such as a film surface. Each data set represents a distinct page or an equivalent body of intelligence and is constituted by a multiplicity of data sub-sets each including at least one data bit. The sub-sets which together form a data set are dispersed on the medium according to a predetermined pattern. The dispersed sub-sets forming the plurality of data sets are interlaced with each other whereby each data set occupies a distinct position on the medium and may be optically extracted therefrom.

Abstract: An animated image presentation apparatus operable in conjunction with a multiple-image microrecord in which a plurality of interrelated images are recorded on a reduced scale in a manner whereby each image is dissected into a multiplicity of bits which are dispersed to form an image pattern that is distinct from and interlaced with the image patterns defined by the recordings of the other images. The apparatus includes a lens matrix disposed in parallel relation to the microrecord to project an image pattern in registration therewith onto a screen, the matrix being constituted by an array of lensettes that are dispersed on the matrix to assume positions that are optically aligned with the bits in the image pattern. The microrecord is indexed relative to the matrix to successively register in a predetermined sequence the image patterns recorded on the record with the array of lensettes for presentation on the screen at a rate providing an animated display.

Abstract: An illumination distribution system for a microrecord reader in which information is optically extracted from the microrecord by a lens array. The microrecord is formed by a plurality of data sets recorded on a record medium, each set representing a reduced scale image of a distinct page of intelligence and being dissected into a multiplicity of data sub-sets which are dispersed on the medium. The illumination distribution system is constituted by a plurality of light-conducting fibers each acting to conduct light derived from a common source to a respective sub-set thereby illuminating the sub-sets of a data set from which information is being extracted, the remaining areas of the microrecord being un-illuminated, thereby avoiding the waste of the available light energy and conserving power.

Abstract: A microfiche or other form of microfilm record having a main set of images thereon which may be selectively projected onto a viewing screen. In order to facilitate the making of reproductions of the recorded images without interposing a mirror between the sensitive film or the plate of the reproducer and the image projection system, the microfiche incorporates a companion set of images each being a reversed image of the corresponding image on the main set whereby when a reversed image is projected, it may be directly reproduced to produce a nonreversed, readable copy.

Abstract: An optical system for reading a microrecord in which a plurality of data sets are formed on a record medium, each set representing a reduced scale image of a distinct page and being dissected into a multiplicity of data sub-sets. The sub-sets, which together form a data set, are dispersed on the medium in accordance with a predetermined pattern, the dispersed sub-sets forming the plurality of data sets being interlaced with each other whereby each data set occupies a distinct position on the medium and may be optically extracted therefrom. The optical system includes an array of lensettes each constituted by a reflective concave element associated with a reflective spherical element, the elements of each lensette being optically aligned with a respective data sub-set whereby the image of the sub-set formed on the concave element is reflected by the spherical element onto a screen.

Abstract: An apparatus for use as both a camera and a viewer. As a camera, light from an object is broken up by a planar array of N lenses into N identical images which fall onto an opaque scene mask. A small aperture lies within each image, but at a different relative zone so that the apertures are non-homologous with respect to the image. The scene mask carries a lens projection adjacent each aperture. A field stop plate is provided with openings which are aligned with those of the scene mask. When used as a camera, light passes through the objective lenses and the two sets of aligned apertures and strikes virgin photographic emulsion. The emulsion is indexed and the process repeated for the next object. After emulsion development, the lensfiche is sequentially illuminated from the rear and each object (macroscene) sequentially reconstructed by projection on a viewing screen. For projection, the developed emulsion is illuminated after turning it about a vertical axis 180.degree.
